Building our own war-robot is quite a fun idea! There are a lot of options, maybe even a little too much when we start the game. It could be better to unlock the ones we can buy as we play.
The first fight after the tutorial is also very difficult! It's a bit frustrating to win the tuto, buy some improvements, and then loose against the first "real" fighter. ^^'
But anyway, this entry is very cool, well done!
